Van den Ende, D.A. (author), Van Kempen, S.E. (author), Wu, X. (author), Groen, W.A. (author), Randall, C.A. (author), Van der Zwaag, S. (author)Piezoelectric composites were prepared by dielectrophoretic alignment of high aspect ratio piezoelectric particles in a thermosetting polymer matrix. A high level of alignment was achieved in the cured composite from a resin containing randomly oriented high aspect ratio particles. Upon application of an electric field during curing of the resin...journal article 2012

Van den Ende, D.A. (author), Bory, B.F. (author), Groen, W.A. (author), Van der Zwaag, S. (author)Composites of piezoelectric particles in a polymer matrix with enhanced properties in the poling direction were prepared by dielectrophoretic alignment of the particles. The effect of processing parameters such as the amplitude and frequency of the applied electric field and the viscosity of the matrix on the dielectric and piezoelectric...journal article 2010

Lau, G.K. (author), Goosen, J.F.L. (author), Van Keulen, F. (author), Chu Duc, T. (author), Sarro, P.M. (author)A powerful and effective design of a polymeric thermal microactuator is presented. The design has SU-8 epoxy layers filled and bonded in a meandering silicon (Si) microstructure. The silicon microstructure reinforces the SU-8 layers by lateral restraint. It also improves the transverse thermal expansion coefficient and heat transfer for the...journal article 2007
